c# – MVC5对象引用未设置为Scripts.Render上对象的实例

我使用 Asp.net MVC5,并没有遇到这样的这个模糊的错误,因为使用Microsoft MVC平台4年以上！错误发生在默认MVC5模板的“管理”页面中.这里的第26行在_layout.cshtml文件中：

Line 24:     <![endif]-->
Line 25: 
Line 26:     @Scripts.Render("~/js/intf")
Line 27:     <script>
Line 28:         if (document.documentMode === 10) {

堆栈跟踪说：

编辑：
当你想要捆绑代码时,我把其中一个放在这里：

bundles.Add(new ScriptBundle("~/js/intf").Include(//first internal scripts
                "~/js/jquery*","~/js/modernizr.js","~/js/ie-prototype-polyfill.js","~/js/prettyPhoto.js"));

注意：如果我评论错误行(样式/脚本捆绑行)错误将是@ ViewBag.Title作为新的错误！我认为Razor视图引擎在这里遇到麻烦,因为它不能实例化视图的代码要求,但为什么？

我知道使用微软技术的一些错误并不与它所说的错误有关.请给我留下你的有益经验.谢谢.

更新：
〜/ views / Account / Manage.cshtml文件的简洁内容可能很有用：

@using Social.Models;
@using Microsoft.AspNet.Identity;

@{
    ViewBag.Title = "manage";
}

<div class="layout-app">

    <div class="row row-app margin-none">

        <div class="col-md-12">

            @if (ViewBag.HasLocalPassword)
            {
                 @Html.Partial("_ChangePasswordPartial")
            }
            else
            {
                 @Html.Partial("_SetPasswordPartial")
            }
        </div>
    </div>
</div>

解决方法

由于我在主版本文件中使用ViewBag作为显示项目页面的必需变量,所以缺少初始化,让我看到这样的错误！迄今为止,我从微软开发技术中看到的一个不相干的错误之一.
